Support device for a display

ABSTRACT

A support device includes a post, a shaft, a seat and a driving member. The post has a top end that is formed with a through-hole extending in an axial direction. The shaft is mounted rotatably on the top end of the post, and extends in the axial direction through the through-hole in the top end of the post. The seat is mounted securely on the shaft so as to co-rotate with the shaft, and is adapted to support an object thereon. The driving member is mounted movably on the post, engages the shaft, and is operable so as to drive the shaft together with the seat to rotate to a desired angular position relative to the post.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a support device, more particularly to a support device adjustable so as to enable a display or a notebook computer to be positioned at a desired angle.

2. Description of the Related Art

Referring to FIG. 1, a support device for a notebook computer 2 includes a base 11, a tray 12, and a support member 13. The base 11 has a top side having opposite front and rear edges, and formed with a plurality of positioning grooves 111 aligned with each other from the front edge to the rear edge. The tray 12 has a bottom side, a pivot end 121 pivotably connected to the base 11, and a distal end 122 opposite to the pivot end 121. The support member 13 includes an engaging end 131 pivotably connected to the bottom side of the tray 12, and an opposite positioning end 132 for engaging selectively one of the positioning grooves 111 so as to position the notebook computer 2 at a desired angle for use or for display.

Although the aforesaid support device is able to support the notebook computer 2 at different angles, in practice, there are still some drawbacks that have to be resolved. In particular, since the angle of the computer 2 to be positioned is determined by the position of the positioning grooves 111, variation of the angle of the computer relative to the base 11 is limited by the number of the positioning grooves 111. Moreover, when the number of the positioning grooves 111 is increased, the shape of the base 11 becomes larger and more complicated accordingly.

SUMMARY OF THE INVENTION

Therefore, the object of this invention is to provide a support device that can overcome the aforesaid drawbacks associated with the prior art.

Accordingly, a support device of the present invention includes a post, a shaft, a seat and a driving member.

The post has a top end that is formed with a through-hole extending in an axial direction.

The shaft is mounted rotatably on the top end of the post, extends in the axial direction through the through-hole in the top end of the post, and defines a rotation axis.

The seat is mounted securely on the shaft so as to co-rotate with the shaft, and is adapted to support an object thereon.

The driving member is mounted movably on the post, engages the shaft, and is operable so as to drive the shaft together with the seat to rotate about the rotation axis to a desired angular position relative to the post.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 2 and 3, the preferred embodiment of a support device for a display or a notebook computer according to the present invention includes a post 3, a shaft 4, a seat 5 and a driving member 6.

The post 3 has a base 31 and a pair of post halves 32 that are coupled to each other to form a post body of the post 3. The post 3 further has a top end that is formed with a sleeve 322 that defines a through-hole 321 extending in an axial direction (X).

The shaft 4 is mounted rotatably on the top end of the post 3, extends in the axial direction (X) through the through-hole 321 in the top end of the post 3, and defines a rotation axis. The shaft 4 has two opposite end portions 42 and a middle portion 41 that is disposed between the end portions 42, that is formed with a first thread 411, and that is in the form of a worm wheel.

The seat 5 is mounted securely on the shaft 4 so as to co-rotate with the shaft 4, and is adapted to support an object, such as a display or a notebook computer, thereon. The seat 5 includes a pair of rod members 51 that are respectively mounted on the end portions 42 of the shaft 4 and that extend in a transverse direction relative to the shaft 4. Each of the rod members 51 has a straight upper end 511, a straight lower section 512 that is opposite to the straight upper end 511, and a lower hook end 513 that extends from the straight lower section 512.

The driving member 6 is mounted movably on the post 3, engages the shaft 4, and is operable so as to drive the shaft 4 together with the seat 5 to rotate about the rotation axis to a desired angular position relative to the post 3. In this embodiment, the driving member 6 includes a screw rod 61 that is in the form of a worm, that extends into the post 3, and that has a second thread 611 which engages threadedly the first thread 411 of the middle portion 41 of the shaft 4 such that rotation of the screw rod 61 results in rotation of the shaft 4. A knob 62 is connected to the screw rod 61, and is disposed outwardly of the post 3 for operating the screw rod 61.

Referring to FIGS. 4 and 5, in use, the notebook computer 2 is seated on the straight upper end 511 and the lower section 512 of the rod members 51, and has an end portion received in the lower hook ends 513. When the knob 62 of the driving member 62 is rotated clockwise or counterclockwise, the shaft 4 together with the seat 5 can be rotated about the rotation axis to a desired angular position. In this manner, the notebook computer 2 can be positioned to any desired angle during use.

In sum, the support device of this invention has the advantages of smaller size and convenience in position adjustment as compared to the prior art.

While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
